Question 9: Weighted Moving Average Calculation 2 6 points A company wants to forecast demand using the weighted moving average. If the company uses three prior yearly sales values (i.e., year 2018 = 113, year 2019 = 91, and year 2020 = 205), and we want to weight year 2018 at 15 percent, year 2019 at 29 percent and year 2020 at the remaining percentage, what is the weighted moving average forecast for year 2021? Please keep two decimals. Locally stored answer: Question 10: Exponential Smoothing 4 points The equation for exponential smoothing states that the new forecast is equal to the old forecast plus the error of the old forecast. Please answer 'True' or 'False'. Locally stored answer: Question 11: Exponential Smoothing 4 points In exponential smoothing, it is desirable to use a higher smoothing constant when forecasting demand for a product experiencing high growth. Please answer 'True' or 'False'. Locally stored answer: Question 12: Exponential Smoothing 6 points Given a prior forecast demand value of 154, an actually observed demand value of 126 in that period, and a smoothing constant alpha of 0.85, what is the exponential smoothing forecast value for the following period?
